ABSTRACT
The article discusses modern technologies for sinking open caissons with a height of more than 15–30 m and a diameter of more than 30 m. The article studies the technological parameters ensuring the increased performance of soil extraction from caissons. The technology for soil transportation by means of belt conveyors mounted with special fastening elements on the inner side of caisson walls is proposed. Thus, several belt conveyors are consecutively installed along the upward helical trajectory along which the soil is excavated to the surface. Further conveyor sections are installed as the caisson sinks.
